MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains embedded links and a visual lure suggesting a download, which is consistent with a phishing or social engineering attack. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect the user to a download site. No scripts were extracted from this sample.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
